E. Coli Update: 90 Cases Linked to McDonald's Quarter Pounders

The recent E. coli outbreak in the United States, linked to McDonald's Quarter Pounders, has affected 90 individuals across 13 states, with the highest number of cases reported in Colorado and Montana. This public health crisis has resulted in at least 27 hospitalizations and one death in Colorado. This outbreak underscores the importance of vigilance in food supply chains and the potential for widespread health implications when foodborne illnesses arise.

According to an update from the Centers for Disease Control and Prevention (CDC) most E.coli cases have been documented in Colorado, with 29 reported infections, followed by Montana with 17 cases. Other states with reported cases include Iowa, Kansas, Michigan, Missouri, Nebraska, New Mexico, Oregon, Utah, Washington, Wisconsin, and Wyoming, as reported by Mexico Business News. 

At least 27 individuals have been hospitalized due to the outbreak, with two cases developing hemolytic uremic syndrome (HUS), a severe condition that can lead to kidney failure. Additionally, one death has been reported in Colorado, involving a resident of Mesa County. This individual was not among those who developed HUS. 

The CDC has stated that the number of reported cases may continue to rise, as it typically takes three to four weeks to determine if an illness is linked to an outbreak. Many cases may go unreported, as individuals often recover without medical care and may not be tested for E. coli.

Epidemiologic and traceback data suggest that fresh, slivered onions used in the Quarter Pounder and other menu items are likely the source of the outbreak. In response, McDonald's has ceased the use of slivered onions on the Quarter Pounder in certain states to mitigate further illnesses. Taylor Farms, the supplier of these onions to affected McDonald's locations, has also recalled yellow onions.

While McDonald's stopped distributing Quarter Pounder beef patties in affected areas, the company is now requesting their beef suppliers to produce a new batch of fresh patties to resume distribution. The Quarter Pounder is anticipated to be available in all restaurants within the next week, reports ABC News. 

The CDC advises anyone experiencing severe E. coli symptoms—such as bloody diarrhea, a fever exceeding 102°F, and vomiting—to seek medical attention promptly.
